> It should not take someone a week to read a research paper Either you have never read a research paper, or you are gifted, or you have been doing that for so long in your field that you forgot how hard it can be when you start.
Before arguing for or against this statement, perhaps we should precise what kind of research papers we're talking about. We're on HN, so I know most comments of this thread are dealing with scientific research papers; I'm a student in humanities myself, so I've never taken the time to analyze such papers and I am thus unable to defend or counter OP's claim on this particular question. However, their comment applies…
However, among my colleagues (all very talented in their own unrelated areas) it generated a fair amount of consternation, because although they had a week to read it, none of them felt like they had a good grasp of it until after I had presented it. The key takeaways that had jumped out at me immediately were lost in the noise.
Whether or not a week is the right time, I can definitely empathize with taking more than a day to evaluate a paper, particularly in an area not very near to your own as there might be a lot of missing background to fill in. In contrast, my PhD advisor could flip through a paper in 30 seconds and pick up the key points it took me an hour to extract. In that sense, I really think that reading papers is a skill that can be trained.
